Fig. 1: Phylogeny and species distribution pattern of Juniperus.

a Phylogeny of Juniperus. BI tree inferred from the whole chloroplast genome along with chloroplast genes of several species downloaded from GenBank. The numbers attached to the branches show the Bayesian posterior probability (PP) and maximum likelihood bootstrap support (BS). The PP = 1/BS = 100 is not shown. b–d The global distribution patterns of species diversity (b), phylogenetic diversity (c), and weighted endemism (d) of Juniperus plotted in grid cells of 1° × 1°. The map was downloaded from the WorldClim (https://www.worldclim.org/).
